My pinhole lens for EOS DSLRs via Kickstarter arrived this week.
This was my eleventh Kickstarter backed project. The creator had had a number of difficulties with the lenses including issues with the fit tolerances to what must have been the the final annoyance for him, many lenses going missing in the post. I have some fine tuning to do to replicate the images that the creator posted when initiating the project, a few of these are in my original post about backing the project.
The pinhole lens has a 44mm focal length and an aperture of f157. This means that only a tiny amount of light reaches the sensors of the digital camera but all the rays of light that do reach the sensor are parallel to each other. This means that the depth of field of the the lens is nearly infinite.
Worldwide Pinhole Photography Day
While waiting for the lens to appear I have been researching what I could do with the lens once it arrived and I came across this website that promotes Worldwide Pinhole Photography Day. In 2015 this was on April 24th (I missed this one!) and in 2017 is on April 30th. Anyone can post images taken on the day and form a worldwide gallery of images all taken using a pinhole.
My first pinhole images
This was taken using my Canon EOS 5D on manual with an exposure of 4 seconds on ISO 100.
I then tried to take other images and soon discovered how framing up the image was now hit and miss. Again, on my EOS 5D with the same settings and a plea to sit still.
Experimenting with the pinhole lens
Online I had read that using a pinhole lens would highlight dust on a sensor and after switching to my EOS 100D, this was indeed the case if you look closely at the images below.
These images were taken with different exposure times all at ISO 100.
Moving across the street I experimented again with exposure times and kept the ISO at 100.
And here’s my ‘cloud’ image on the EOS 100D exposure of 1/2 a second at ISO 100.
